To all whom it may concern.

'Be it known that I, WILLIAM H. KING- ,STDN, a citizen of the United States, residing at New Haven, in the county of New Haven and State of Connecticut, have in vented certain Improvements in the Manufacture of Celluloid-Covered Articles, of which the following description, in connection with the accompanying drawings, is a specification, like reference characters on the drawings indicating like parts in the several figures.

This invention relates to the art of covering articles with celluloid or other pyroxylin material which is capable of being rendered flexible or plastic so that it may be shaped about and united to the .surface of the article, or the part of the article, which is to be covered.

The invention is herein illustrated as applied to the manufacture of covered lacing hooks, although many of its features are capable of a more general application.

In one of its important aspects the present invention comprises a novel-method of covering articles with celluloid. The invention also includes within its scope a machine whereby this novel method may be practised in a satisfactory manner upon a commercial scale, but the machine may be used in the practice of other methods than that herein disclosed while the method itself may be carried out by the use of machines or apparatus of many different types as will be apparent to those skilled in the art.

One object of the invention is to provide a machine which shall be capable of continuous and automatic operation and which shall require little attention on'the part of the attendant beyond supplyin in bulk the articles to be covered and the celluloid to constitute the covering.

To this end an important feature of the invention consists in the combination of a pair of cocperating dies with mechanism for feeding a metallic blank and a blank of plastic material to the dies, means for heat-- ing the dies, for applying pressure tov them and for releasing the pressure after the dies have sufliciently cooled.

The invention is herein shown as embodied in a machine for covering lacing hooks with celluloid and for convenience the articles to be covered are hereinafter referred to as metallic blanks and the covering material is referred to as celluloid although, as

has already been stated, the invention is capable of adaptation for covering a 'vavriety of articles with celluloid or other plastic material.

Another important feature of the invention consists in the combination with a number of cooperating dies of mechanism for moving the dies in an endless path and for successively supplying to said dies during their movement in such path a metallic blank and also a plastic blank.

In a preferred embodiment of the invention the dies are moved along a heated guideway, which constitutes part of their path, until the celluloid is sufliciently heated. They are then moved along another portion of the path in which movement they are subjected to pressure, cooled and released from pressure.

In the embodiment of the invention herein shown a series of moldscomprising one or more pairs of cooperating dies are arranged for movement along a straight guideway which is disposed as the diameter of a carrier ring having sockets arranged to receive successive molds fromone end of the guideway and carry them one by one to the other end of the guideway. During the movement of the molds along the guide-way the metallic blanks are supplied and then plastic blanks are supplied, and the molds are heated. During their movement in the car rier ring the molds are subjected to pressure and carried while under pressure along a path sufficiently extendedto permit them to cool. The pressure is then released and the dies reintroduced into the straight guide way where the finished hooks are ejected. This arrangement broadly constitutes an important feature of the machine and renders possible the desired uninterrupted and continuous cycle of operations. A's'will be apparent hereinafter the separate steps of the method are so related that they may be performed to the best advantage when each individual mold occupies successively progressing positions in its endless path.

Another object of the invention is to provide a machine of the class described which shall be adapted for receiving its supply of celluloid or other plastic material in the form of a continuous strip, wire or rod I nismj for feedinga celluloid rod or'wire, cutting it into pieces of suitable size and de livering the pieces so cut successively to forming dies. i

rather than in the form of previously prepared pellets. It is believed that it has not heretofore been found practical to utilize celluloid in this forn in a covering apply ing machine. It Will be apparent that such amachine possesses many advantages in point of simplicity of organization and operation over a machine in which .it is necessary to provide magazines, raceWays and transfer ring mechanism for celluloid pellets.

An important feature of {the invention consists broadly in the provision of mechayO'ther features of the invention relate to feeding and cutting off mechanism for the .celluloid rod, or Wire,,e'Xamples of Wl'11Ch'-.

mechanisms are disclosed specifically hereina fter'. As herein shown, the celluloid rod or Wire is fed through a passage disposed at an angle to the path ofacutting off knife and is advanced a toothed wheel'which is disposed with its periphery extending into the passage so as toengage the celluloid between-itself and theopposite side of the passage. For convenience in h'andling celluloid rods of different diameters the feed Wheel and guiding passage are. preferably arranged for adjustment relatively to each other. Feeding mechanism of this'kind'has proved reliable and accurate in operationand admirably suited to-the performance of its function. That feature of the invention Which relates to the cutting mechanism consists in providing a member having a shear ing blade and a transferring rib or bar, the

shapeof the blade being'such as to shift therod' into alineinentf With the transferring bar duringthe cutting operation and being beveled on the side toward the end of the red, :A cutting device of this character 0perates to sever a piece from the end of the rod cleanly and Without tendency to break the rod and it is also'an advantageous construction in that it presents a simple and effective transferring device for carrying the severed end of'the celluloid rod to the mold to be supplied. y v

The invention. also includes anew and im proved mechanism for feeding hook; blanks from the mass contained in a hopper and delivering them singly to the successive forming dies. 'As herein shown one member of eachpair of dies is arranged to be moved beneath the delivery end of a raceway tin such "position as to receive a hook blank with "its barrel disposed horizontally. A

' 'e'n'ol'v between the delivery end of the racepair of guiding plates are arranged end to \vay andthedie and retain'each hook blank as it is released from the raceway, maintaining it"in positionto be engaged and forced between the ends of the guiding plates to its seat on the die'by a reciprocatory transferring plunger. By this construction a po'sitiveand accurate handling of the hook blanks is insured and'moreover the operation of this transferring mechanism is not nary variations in the dimensions of the hook-blanks encountered.

The operation of theltransferring mecha nism is rendered more certain and precise by its combination With-devicesfor locating the die to receive the hook blank in exact alinenient With the transferring plunger'and' such combination constitutes another fea- As has already been stated, the hook covf ture of theinvention.

ering process is carried out as a continuous 3 operation, its successive steps being per 7 formed hwhile the'dies occupy successive positions in an endless Path. The metallic blank feeding mechanism. andfthe celluloid feeding and cutting off mechanisms con- I stitute some of the instrumentalities which effect successive steps in'theiprocess. at different points-in] the-path of the molds. \Vhile these instrumentalities in themselves constitute important features" of the 'inven an organized machinealso constitute. important featureLof the invention, and: the same is true ofeach 'of the other instrumentalities which operate at "subseq points in the path of the molds.

After themolds have been supplied With blanks'they' are'advanced through achama uent ioo

ber filledwith steam above aheated'guide Way. The combination of such a chamber With molds, blank supplying mechanism and mold feeding nechanism constitute another important feature of the invention.- The advantages of this construction as-a means for. heating and softening'celluloid are apparent but it has pa'rticular'advantage in the presentcombinationjin that it lends itself particularly Wellto the requirements of the'process to be carried out and coeperr ates to a good advantage With the other in- I strumentalities of the machine. The construction 'of' the carrier ring and itssupporting'and feeding mechanism con stitute another feature of the invention Which contributes largely to the smooth and successful operation ofgthe .machine as a I Whole. The'W-eight of the carrier ring is distributed,so as to avoid excessive friction,

partly upon a stationarysupport and partly r upon a nun 'berof separated roller bearings and an intermittent rotary movement 18 1111 parted to the ring' 'by feeding means acting simultaneously at diametrically opposite points.

' Other features ofthe invention relate to the devices for subjecting the molds to pressure and holding them under pressure until the molding operation has been effected. As

v interrupted or? interfered With by'anyorditermined pressure upon the molds and are locked in a position of pressure. This construction is important in that it insures a uniform treatment of each article covered, a factor which contributes to uniformity of roduct.

- WVhile the advantages of the other instrumentalities of the machine, for example the pressure actuator for the mold plungers, the mold feeding mechanism, mold cleaning mechanism, the devices for separating and closing the separate dies of the mold. etc.,

are not enumerated at this point, it should be understood that each of theseinstrumentalities possesses qualifications and advantages by reason of which it is particularly adapted for use in the present organized machine, and that, further, each of these instrumentalities in itself comprises a new and useful device or appliance which may be embodied to good advantage in covering applying machines of a different type from the machine herein disclosed.

The novel method, for the practice of which the machine herein described may be used to a good advantage, consists broadly in subjecting the celluloid blank to the softening influence of moisture and heat, for example as by steaming, and then shaping the celluloid by pressure in forming dies upon the article to be covered. Preferably the celluloid is allowed to cool before the dies are separated but this is not essential to the method. It has been found that the method above outlined results in an improved product and also renders the shaping or forming operation more easily effected.

The construction of a preferred embodi- 11161113 of the machine and the nature of the novel method will be best understood and appreciated from the following drawings, in which,

Figure 1 is a view of the entire machine in side elevation; Fig. 2 is a plan view; Fig. 3 is a view in perspective of the blank supplying mechanism; Fig. 4 is a detail view showing a die in blank receiving position at the foot of one of the raceways; Fig. 5 is a. view in .elevation of the feeding and cutting mechanism for the celluloid rod; Fig. 6 is a View in perspective of the feeding mechanism shown'in Fig. 5; Fig. '4 is a partial view in perspective of the cutting devices and the guideways for the celluloid rod; Fig. 8 is a. sectional view of one of the press castings; Fig. 9 is a perspective view, of the delivering end of the guideway and part ofthe carrier ring; Fig. 10 is a view in perspective of the mold pressing plunger; Fig. 11 is a fragmentary view in perspective of the press actuating mechanism; Fig. 12 is a sectional view of the mold cleaning device; Fig.1?) is a fragmentary view in perspective of part of the mold feeding mechanism; Fig. 14 is a fragmentary view in perspective of part of the guideway; Fig. 15 is a fra mentary view of the carrier ring and its feeding disk; Fig. 16 is a sectional view of the carrier ring and its supporting flange; Fi 17 is a sectional view through the guideway for the molds, and Fig. 18 is a fragmentary view of the mold locating device adjacent to the delivery end of the guidewav.

The operation of the machine will be best understood from a brief description of its general structure, with reference to the drawings, and of the manner in which its different instrumentalities cooperate. The machine has a horizontal heatedguideway 2 along which is moved intermittently a series of molds 4 each having two pairs of cooperating dies and being each arranged to receive a pair of metal blanks from a pair of raceways Sleading from hoppers 8 in which the blanks are contained in bulk. After the hook blanks have been supplied to the molds the latter are advanced a few steps and then a celluloid blank is delivered to each pair of dies. The molds have hook receiving or throat dies 10 pivoted to each side and arranged at times to stand in a vertical position and receive the hook blanks with their open sides down and barrels horizontal. Each mold has also two dies 12 shaped to form the outer part of the heads of the hooks and these dies are located in the bottom of the mold in such position as to register with the head of the hook when the throat or receiving dies 10 are folded into a horizontal position. The celluloid, in the form of a rod or wire, is fed from each side of the guideway through tubes 14,

pieces being cut from the end of the rods in just the proper size to form the celluloid cover of the hooks andleave no waste, and one of these pieces is placed automaticallv in each of the lower or head dies 12. After the celluloid blanks have been so received the throat dies 10 are folded down noon the head dies and then the molds are advanced sockets in its circumference and each shaped to receive a single mold. When a mold has reached the end. of the guideway 2 it is pushed into a recess in the ring and carried thereby step-by-step circumferentially back to the other end of the guideway. When the has been carried one step. by the .rlng 1t is; automatically-- subjected to pressure and clamped under pressure by the plunger,20 (Figs. 8 and 9)v which is forced 7 the vertically reciprocating plunger 25.

*downwardlyand locked by an eccentric lever 22 actuated in turn bythe arm 24. of A curvedwvedge. cam 26 serves. to swing the levers 22 upwardly as they approachthe end of the guideway so that pressure on themolds is released before this point is reached. V Vhen the. ring 18 stops with a mold opposite thereceiving-end of the guideway the mold is pushed into the guideway byats corresponding ejector plate 28 actuated by the reciprocating sllder 30. Wedge earns 32 on either side of the molds then swing the hook dies up. into a verticalpoand pass to a receptacle.

sition with the finished hook thereonland other wedgecams 3&jstrip the hooks from the dies, whence they fall into, chutes 36 Having now briefiyoutlined the general operation of the machine its various parts and instrumentalities will now bemore specifically described. I

The frame of the machine. comprises a heavy circular flange 100 supported at a -convenient height by legs '101 and having integrally formed therewith the diametrical bars 102 and 103 disposed at right an'gles to each other. The bar 102 is grooved centrally to receive a guideway 2 for the molds which is chambered (see Fig. 17 and'connected with a steam supply pipe 105 andan exhaust pipe 104 whereby it-ma'y be maintained at the proper temperature'ito soften the celluloid. A-shaft 106 journaled in bearings on the frame beneath the, bar 102 is arranged to actuate the moving parts of the machine and may be driven by a pulley 107 on one end from anysuitable or con- A portion-of the outer tionary flange is cutxawayto form a peripheral channel in which is journaled the rotatable carrierring 18, see Fig. 16. The

,ring 18 has a projecting shoulder which extends downwardly onthev outer, edge of the flange 100 and flush withits lower surface To this shoulder are rigidly attached the segments of another ring 108having cut in'fit's inner edge alternateradial slots i 109 and segmental recesses. An adjustable roller bearing 99 for thering is arranged on each leg ofthe frame. 1

The ring 18 is intermittently rotated and locked between each; step by apin 111 and I segment 112 respectlvely mounted on a rotat-able disk 113. The pin. 111 first engages a s'lot 109-and advances the 'ring '18 one step while the cut away portion of theseg- I ment is turned toward the ring and then the curved portionof the segment engages the following segmental recess .andlocks the plates 18 is limited by surface of the sta ring against, movement until thep-in is I moved to act again. One disk 113 islocated I at eachside of the ring andthese disks. are

rotated simultaneously from the actuating shaft 106 through the two. gears 115, transverse shafts, 116, bevel gears1-17, bevel gears I 118 and vertical shafts 119'to the upper end of which are rigidly secured the disks; 113.

In the upper surface ofthering 18: are

formed a series of radial slotseach shaped at its inner end to receive a mold 4 and having an ejector plate 28 slidingly-arranged in its outer portions, the tails of the plates ring 18. Radial movement of the ejector tion. not shown.

The guideway 2 and the sockets or; re cesses' in one side of the. carr1er ring 18 are kept full. of molds, the line of molds be ng intermittently advanced along the guide-. way from the end at which they are received from the ring 18 ,to the end at which they are delivered. It is understood that when the ring is locked between each step there is one recess or socket inregister with each end of the guideway 2. .A=,mold ispushed into the guideway from the ring by the fol lowing mechanism :+-A .bracket 120 having 'ahorizontal guideway in its, upper surface is bolted to the under side of the. bar102 I projecting without the circumference of the I 3ov a slot and pin connecn adjacent to the right side of themachine v (Fig. 1) and. in this guideway is slidingly .mounteda plate 30 having a vertical stud 124: at its outer endlocated in longitudinal alinement with the guideway 2 and the path of the particularejector- 28 which happens to be in delivering position. The bracket has downwardly projecting ears in which. is w mounted an angle cam lever 126 engaging at its upper end in a slot in the'slide plate 30 and having a roller 128 at its lower end which cooperates with a surface cam 130- on the" shaft106. It will .be seen that'when the clam lever 126- is swung outwardly at its lower end and the plate30 moved .inwardlv,

the stud 124: will engage and force inwardly the ejector 28 thus pushlng the mold located in frontof it from its recess in the carrier ring 18 into the receiving, end of the guidev way 2.

It will be apparent that thewhole line ofmolds will be advancedinf the. guideway 2 at the same time a distance equal to v the width of one mold. 'Reverse movement of the cam lever 126 and slide plate 30 is caused by the action" of a tension spring 132 extending between the lever 126 and a stationary-bent arm 134. bolted or otherwise so; cured to the bracket 120. f

i In order 'toinsure positively that amold shall not project inwardly. from its recess and strike the end of. the bar 102 in moving into line with the guideway, thereisprovidedwithinthe ring 18 and adjacent to its inner edge,a guard 136 which acts positively,

as the molds are moved relatively to it, to force each mold outwardly into its recess. In order that each ejector plate'28 mayalso be retracted there is provided an arm 188, see Fig. 13, on the upper end of the stud 124 and this arm carries a wedge earn 140 which acts successively upon each ejector through a stud 141 set in the latter. Under each ejector plate and recess is formed a channel inclining outwardly in the ring so that dirt, pieces of celluloid, or other obstruction will tend to fall out of the ring. This effect is assisted by a blast of air delivered intermittently from a pipe 142 as each channel comes into register with it.

The construction of the molds is well shown in Fig Each mold comprises a short bar having the upstanding ears 145 and flanges 144 at either end, the latter being shaped to fit undercut ways in the recesses of the carrier ring 18 and also in the sides of the guideway 2. The bar is beveled between the ears 145 and notched at its lower edges, the notches in two adjacent molds forming an opening leading to the bottom of the guideway 2.

Between each pair of ears 145 is pivoted a throat die 10 which is formed in a plate pivoted on a horizontal axis between its ends and has a rounded tail projecting outwardly from its pivot. The inner end of the plate is shaped to mold the celluloid covering properly about the inner surface and edges of the head of the hook blank. 1n the bottom of the mold are located the concave dies 12 before mentioned. These dies are formed on separate studs set in the bottom of the molds and have projecting portions 13 at their inner sides which shape the back of the head and neck of the hooks.

The hooks are supplied in pairs simultaneously to the hook dies of each mold while the mold is held in position below the lower end of the raceways 6. Projecting upwardly from the bar 102 is a yokeshaped bracket 146, see Fig. 8, to which is attached ablock 148 having three vertical guideways formed therein for two hook conveying plungers 149 and a mold locating plunger 150. A second bracket 152 secured to a block 94 supports the rear portion of said block 148. The lower ends of the raceways 6 are connected to the block 148 and pass one on each side of the rear bracket 152. Secured to the under side of the block 148 is a rectangular frame 154, see Fig. 4, of a width equal to the distance between the hinged hook dies when the latter stand in vertical position. The sides of the frame project below the top of the hook dies in the guideway 2 and the dies are pressed inwardly against the frame by leaf springs 156 as the molds are moved past the frame so that the lateral position of the hook diesis determined with accuracy. A horizontal guideway is'formed in each side of the block 148 just above the tops of the hook dies and in line with the raceways- In this guideway are located a pair of plates 158 and 1.60 which are yieldingly held in contact at their proXimate ends by springs 162 and 164 respectively. The upper adjacent corners of the plates 158 and 160 are cut away to form a depression or recess adjacent to the bottom of each raceway into which successive hooks pass from the raceway when released by the let-off mechanism. After a hook has been delivered to the recess at the upper edge of the plates 158 and 160 it is forced downwardly between these plates and seated on a hook die by the reciprocation of one of the conveying plungers 149, the plates yielding apart su'liiciently to permit the passage of the hook but still preventing it from turning in transit. The conveying plungers 149 are connected at their upper ends to a plate 223 carried by a cross head 162 in such a manner as to perunit a vertical yielding against the compression of springs 166 in case an imperfect hook or other obstruction is. encountered.

Connected to the plate 223 on the cross head 162 between each pair of conveying plunger-s 149 is the forked mold locating plunger 150 also arranged for vertical yielding movement, similarly to the conveying plungers by the interposition of a spring between it and the plate 223 and having its operative end in advance of the ends of the conveying plungers 149. The cross head 162 is reciprocated through the side rods 168, the lower cross head 170, and the eccentric rod 172 by the eccentric 174 on-the actuating shaft 106. W hen the cross head is moved downwardly the forked ends of the plunger 150 first engage the beveled sides of the mold, which has been advanced into approximate position, and shift the mold accurately into its proper hook receiving position. In its continued motion the cross head acts to compress the spring 151 thus holding the plunger forced against the mold and so looking thelatter in position. The conveying plungers have meanwhile begun to act in the latter part of the stroke of the cross head; these carry the hook blanks to the hook dies and force them to their seats.

The frame 154 has grooves in its sides located behind the abutting erids of each pair of plates 158 and 160 to permit the passage of the head of a hook blank. The upper portion of each conveying plunger is square in. cross section to fit its guideway in the block 148 but at its lower or hook engagement end'it is provided with a fiat blade 176 arranged to overlie the head of a hook blank. a reduced portion 178 arranged to fit into the depression in the back of the neck of the hook and a forked piece 180 arranged to engage the barrel. of the hook. A vertical leaf spring 182 is secured at each side i oi theblock 148 in. position to engage the controlled at every point in its end of the barrel oft hook blank as itis delivered to the recess between the plates 158 and 160 to prevent the hook from being displaced. It will be seenthat each hook is 1 securely grasped and its position definitely passage from the recess to the hook die.

The hook blanks are supplied to the upper end of each raceway '6 from hopper S in which is. arranged a rotatable separator plate of any desired construction. Pawl and ratchet mechanism is provided for rotating the separators and is driven from a crank disk 80 on the end of the shaft 106 1 through a connecting rod 82and plunger "84 'by gravitythe lowermost hook being armounted for vertical reciprocation in bearings in the standard 86 which carries the hoppers 8, The hook blanks descend the raceways 6 rested by the pointed end of an arm 1'84 pivoted on the lower rail of each raceway.

- The arm 184 is connected with an oppositely arranged arm 186 pivoted on the upper rail ot the. raceway by means of a bridge piece 188. The end of thearm 1865is arrangedto enter the space between the lowest two hooks on the raceway and prevent the whole line from passing down when the lower arm 184 swung downwardly to permit the escape of thelowest hook. The arm 186 is formed as a bell crank lever and its upwardly 8X- tending arm has a pin and slot connection with a bell crank lever 190 pivotally mount- I ed upon the sides of the block 148. The upper arms of each lever. 190 are hookedand extend into the path of movement of'a pin 90 set in the outer side of each transferringv plunger 149, see Figs. 3 and 5, so that at each upward movement of the latter the one hook is released by the let-off arm 184. Rs

, verse movement of the levers 190 and conse quently the let-ofi' arms is caused by a pair of spring plungers 192 each having a transverse pin 194 engaging the under side of the horizontal arm of one of the levers 190.

' ranged to lock the arms of the levers I devices for supplying the celluloid blank required for covering theblanks. These devices will now be described. On either side of the guideway are arranged guiding tubesv 200 which direct the celluloid in'the form of a small rod or wire from coils, not shown,

to the toothed feed wheels 202. The feed Wheels are mounted upon short spindles 204 no opportunity for the each journaled in bearings formed in'a pl'ate 205' adjustably mountedfonla standard bolted to the bar: 102 and each-spindle is provided at'its outer end with'a ratchet wheel-208 through which the spin'dleand its feed wheel is rotated step-by-step to advancej the celluloid to the cutting off point.

;The ratchet wheels are rotated simultane-- ously in opposite'directions bydogs 210 each of which is-pivoted to 'a segment 212 projecting upwardly from a sleeve 214lo'osely mounted on the spindle '204. Projecting from the sleeve 214': in'the rear of the-segment is a roller'army216 carrying a cam roller which coeperates with a. cam 218 car-- riedby a slider plate 220 arranged for vertlcal reciprocation in ways cut in the-outer side of the standard 206 and connected by a rod 222 to the plate 223 on the cross head 162. cam'2l8 acts to throw theroller arms out- Qwardly and swing thejsegmentscausing the dogs 210-to rotate the ratchetwheels When the cross. head and cam descend the tension spring 224 causes reverse movement of'the WVhen the cross head is elevatedthe roller arms and the dogs are carried idly over a tooth on eachr'atchet wheeL- If it should be desired-to throw the feed wheels out oi operation the roller arms are pulled apart and locked out .of the path of the cam by alatch 226 pivoted to one arm and having a notched end to engage a pin on the other arm.

. A horizontal guideway ortube 14 of circular cross section for the celluloidis formed beneath each feed wheel," the latter being arranged to engage the stock between its teeth and the bottom of the tube, advancingit andindenting it at each intermittent move ment. Each tube at its inner end intersects a vertical passage in which reciprocates a cutting plunger 230 connectedat its upperend to the plate 223 and actuated byithe-reciprocation of the cross. head 162. The rotation of the feed wheel advances the end of the celluloid'rod across the vertical passage bringing its end into contact with the face of thecentral, partition or abutment 232 between the two passagesl The end of the rod is sheared oflfby thecutting plunger against the lower inner edge of the tube.i14, being thereupon carried downthe vertical passage andv deposited in one of the concave dies.

The ends ofthe verticalpassages extend into closeproximity to the dies so:thatthere. is. celluloidblankto be come displaced. I a V The lower ends of the cutting off plungers 230 are inclined having their. longer sides "disposed, toward the center of the machine and sharpened to forma cutting edge by being bev'e'ledon their inner sides. Adj-a.-

cent to their longersides'eachplunger has a rib 231, its thickness from :back to front being slightly less than the diameterpofithe celluloid rod to be handled. A. stationary leaf spring 234: is attached to the front of the standard 206 and has a finger pressed resiliently against the rib or reduced port-ion of each cutting plunger. When the cutting plunger is forced downwardly the inclination of the cutting edge causes the celluloid rod to be forced toward the rear side of the vertical passage into alinement with the shoulder formed by the end of the reduced portion of the plunger and by this portion the celluloid. blank is transferred past the leaf spring 234. When the blank passes this spring it snaps inwardly against the side of the reduced part 231 of the plunger and in so doing imparts.

an added downward impulse to the blank. It also acts as a stripper and prevents the plunger from carrying the blank upwardly from the concave die in case the blank should stick to the plunger.

After the molds have been supplied with celluloid blanks they are advancedalong the guideway 2 under the cock 250 of a Water pipe and a drop or two of water is allowed to fall into the V-shaped channel formed by the adjacent beveled sides of the molds, the

' water finding its way to the'bed of the heated guideway through the apertures formed by adjacent notches before mentioned. This water is carriedalong by the molds, being vaporized in its passage along the guideway and acting to soften the celluloid and render it fit for molding. After passing the cool 250 the molds pass under a pair of wedge earns 25% which engage and fold inwardly the hook dies carrying with them the hook blanks which are lowered into place upon the celluloid blanks in the concave dies, although no pressure is applied at this time. Guides 256 are disposed adjacent to the cams 254: being shaped to fit in the groove in the back of each hook blank and run in said groove while the hook die is being folded inwardly and at the same time being advanced. The shape of the guard therefor approximates a helix. After the molds pass the cams 254 they traverse the remaining length of the guideway 2. and the celluloid is heated meanwhile. After the hook dies have been folded in on the concave dies the hook barrels project vertically. They then travel. along the outer edges of a bar 260 suspended from bridges over the center of the guideway 2 and having a tapering end to guide the barrels outwardly so as to seat the blanks firmly on their dies. The body of the bar holds the blanks in this position and also prevents the hook dies from tilting upwardly in their passage along the raceway.

In order to form in effect a steam chamber where the celluloid may be subjected to the softening influence of the steam generated by the water dripped from the cock 250 on the heated guideway 2 there are provided sheet metal covers 40 which extend above the lVhen a mold has been advanced to the end of the guideway 2 thenext step takes it into the recess in the carrier ring and it then begins its circumferential journey to the other end of the guideway 2. In making its first circumferential step the mold is carried past a spring pressed plate 264 with a curved outer end which acts to press the mold outwardly into its seat and insure its proper location before it is subjected to pressure see Figs. 1 and 18.

Bolted to the upper surface of the carrier ring is a series of press castings 270, each extending over two adjacent radial slots and recesses and having a pair of vertical bores in which are located the pressing plunger-s 20, see Fig. 8. Each plunger is located above the dies of the mold in the recess into which the bore of the plunger opens and the plunger has a pair of holes drilled into its lower end, see Fig. 10, to receive the barrels of the blanks held inthese dies. Adjacent to each hole is a projection 27efshaped to fit into the groove in the back of each hook blank and prevent the celluloid from spreading down this groove and also to form a square shoulder in the applied celluloid at the proper point. Above the plunger 20 may be located a stiff compression cushion of any preferred form. As herein shown this comprises a head 275 a stiff compression spring 276 and a loose washer 27 8 held in position to keep the spring under considerable pressure by a bolt 280 threaded into the head 27 5. The head of the bolt 280 is received in a hole in the upper end of the plunger 20 when the cushion is subjected to pressure and thereby contracted; A lever 22 is pivoted between ears onthe press casting and has a hardened eccentric portion 28% arranged to engage and depress the head 27 5 and thereby force down the plunger 20 when the lever is swung into a position inclined downwardly toward the center of the carrier ring.

Each plunger 20 is normally maintained in its highest position by a compression spring285 which acts against one end of a transverse pin 286 projecting through the counters-- an inclined guard 288 which- ;will act positively to elevate the-pin 286 and its plunger in ,caseone of the springs.

285 should become broken or the plunger remain in its lower positionfor any other cause.

Each lever pressure when it is at rest after makingits f first circumferential step'from the delivery 1 end of the. guideway 2.

To this end a plunger is arranged to reciprocate verticall-yin bearlngs formed in a casting bolted to the bar 102 and is provided with an out ward extending arm 24. An angle contact ment of the lever is effected by the engage ment of another flange on the .edgeof the plate with the'lever. This construction results in a longerdriving stroke than would be possible with a flat arm alone. The plungel. 25 is reciprocated from a short counter shaft geared to the actuating shaft 106 and having a crank disk. 300 ,and crank rod 302,

shown in Fig. 1. After the molds leave tent. manner, along a path extending for about one third ofits Icircumference,being cooled while under pressure in the r moveinent along this path. Before each mold arrives at the receiving end'of the guideway 2 its pressing. lever is moved into engagement with a .curved wedge shaped'unlock ng cam 26, see Figs. 1 and 2, and is swung upwardly thus relieving the pressure on the I mold. The'guard 136, before mentioned, ex-

tends from thepoint atwhich each mold is unlocked to the receiving end of the guide way 2 and prevents displacement of a mold from its socket after it has been released from pressure. 'A- plunger lifting safety guard 137, similar to the guard 288, above described is located adjacent to the receiving end of the 'guideway and serves to positively lift each plunger 20 byits pm, 286 in. case of the failure of the lifting spring 285.

When a mold has been brought into regis ter with the receiving end of thegu'ideway.

2 the slider 30 is actuated to pushit into the guideway in the manner already explained.

On either side ofthe guideway adjacent to itsreceiving end are dlsposed blocks 32 having downwardly inclined cam surfaces arranged to engage the outer ends of the throat dies 10 as each mold is advanced and'swing the dies in a vertical position with-the finished hooks on them.

' i In the rear of the blocks 32 -as shown in 22 is swung into its position of position and advanced in this position to v the point *at which 1 they are subjected to pressure they are conveyed by thecarrier ring 18 in an intermit of said blanks.

cated directly over the path of the molds and between the vertically disposed throat which are then free to ran into chutes 36 whereby they may be conducted to any con venient receptacle beneath. the machine. Theblocks 42 and 44 form a narrow channelv through which the throat dies mustpass and dies, act to remove the completed hooks V a curved spring wiper or stripper 46 is an;

ranged above the path of the throat ,dies to further assist in the stripping operation. and in clearing the'dies of bits of celluloid which might cling to their upper edges. In
